USER MANUAL
Product introduction
A Pulse Oximeter is a common device used to check oxygen
saturation (SpO²) and pulse rate.
It is a compact, reliable and durable physiological
monitoring device featuring an OLED display and powered
by batteries (not included).
Intended use
The Pulse Oximeter is reusable device and is intended for
spot checking the pulse oxygen saturation and pulse rate of
adults.
It should not be used for continuous monitoring – this
should only be done under the guidance of your doctor.
Restrictions
Use of the device is for adults only.
Please do not use the device for children, infants and
neonatal. The product is not suitable for children under
3 years because of choking hazard.
Safety instructions
The person using the Pulse Oximeter must have read the
instructions for use carefully.
This product s hould only be used to give an indicative or
reference reading. It should not be used to determine a
diagnosis without consultation with your doctor. Longer
term or ongoing use should only be under the guidance of
your doctor.
If you experience any discomfort in use, please stop
immediately and seek medical help.
When using the Pulse Oximeter the user should pay
attention to, and guarantee safety of the patient being
measured.
The Pulse Oximeter does not feature an alarm function. It
should not be used for continuous monitoring for an
extended period.
Damaged skin tissue can not be measured.
Do not use the device if it has been damaged in any way.
Do not use the device in any way other than that described
in this manual.
Do not to use the Pulse Oximeter during MRI (magnetic
resonance imaging) scanning or CT (Computed
To m o g ra p h y ) environment as the induced current could
potentially cause burns.
The device should not be modified, repaired or serviced in
any way by the end user.
Do not use the Pulse Oximeter in the presence of
flammable anesthetics, explosive substances, vapors or
liquids.
Ensure the device is always clean and free from dirt before
use.
Before cleaning the device, ensure it is turned off.
Do not use high pressure or high temperature to disinfect or
clean the device. Never use cleaning agents/disinfectants
other than those recommend ed.
The device is a factory sealed unit. Keep its surface dry and
clean, and prevent contact with liquids.
The Pulse Oximeter is precision device. Avoid pressure,
knocks, strong vibration or other mechanical damage.
Please store safely when not in use.
For disposal of Pulse Oximeter and ac cessories, follow local
regulations regarding disposal of such a device and
accessories. Do not dispose of randomly.
Use AAA alkaline batteries. Do not use carbon or poor
quality batteries. Remove the batteries if the product will
not be used for an extended period of time.
Avoid exp osure to static e lectri city before using the Pulse
Oximeter.
When in use, keep the device away from radio receivers.

equipment can affect the normal use of the pulse oximeter.
Storage environment
The Pulse Oximeter should not be close to or stored with
other equipment.
Always store the device and small parts such as batteries
out of the reach of children.
Always ensure suitable supervision of patients or others
where the device is used on a lanyard.

Description of the product
POWER / FUNCTION BUTTON
Function description
The Pulse Oximeter is used to measure arterial oxygen
saturation (SpO²) and the pulse rate. Oxygen saturation
indicates the percentage of haemoglobin in the arterial
blood that is loaded with oxygen.
The Pulse Oximeter uses two light beams of different
wavelengths for measurement. These light beams strike the
inserted finger inside the housing and are put in relation to
each ot her during measurement. The arterial oxygen
saturation is then calculated and displayed on the Pulse
Oximeter.

Measuring steps
Remov e the battery compar tment cover and insert the
batteries as shown in Figures 1.
Securely re-fit the battery compartment cover.
Squeeze one end of the device to open it and place an index
finger i nside. Allow the device to gently close on the finger
as shown in Figure 2. (Index, middle or ring fingers can be
used for a reading)
Press the power / function button on the front panel to
switch on the device. Keep the finger and device still with as
little movement as possible and allow the device to take a
measurement.
Ensure the finger is inserted far enough into the sensor so
that the fingernail is just opposite to the light emitted
from the sensor.
Figure 1 Figure 2
Do not perform SpO² monitoring and NIBP (Non-invasive
blood pressure) measurements on the same arm
simultaneously. Obstruction of blood flow during NIBP
measurements may adversely affect the reading of the
SpO² value.
Do not use the Pulse O ximeter to measure patients whose
pulse rate is lower than 30bpm, as this may cause incorrect
results.
Ensure there is no contamination and/or scar on the tested
finger as the result i ndicated may be incorrect due to the
signal received by the sensor being affected.
When used on various patients, the product is prone to
cross contamination, which should be prevented and
controlled by the user. Disinfection is recomm ended before
using the product on other patients.
The highest temperature threshold of the sensor contacts
with a patient’s skin is 41°C.
Repeat use may req uire the us e of di fferent fingers to
obtain a m easuremen t.
Factors affecting measurement accuracy
Incorrect placement of the finger may affect the accuracy of
the meas urement.
The measurements also depend on absorption of a special
wavelength ray by oxidized hemoglobin and
deoxyhemoglobin. Concentration of nonfunctional
hemoglobin may affect the accuracy of the mea surement.
Always consult a doctor if in doubt.
Shock, anem ia, hypoth ermia and the application of
vasoconstriction drug may decrease arterial blood flow to
an unmeasurable level.
Pigment, or deep color (for example: nail polish, artificial
nails, dye or pigmented cream) may cause inaccurate
measurements.
Rotate the display
To r o t at e th e d i sp l a y fo r c o n v en i e n t r e a di n g , when the
result has been displayed on the screen, short press the
“POWER/FUNCTION” button once.
Auto switch off
The product will switch off automatically after 10 s econds
of no sig nal being detected.
